ColorQuartet and device-independent color

ColorQuartet makes use of the CIE Lab color space, which gives you two important advantages:

• the ability to calibrate your scanner according to the device-independent IT8 standard.

• the ability to use ICC output profiles from other color management systems – with or without

additional modification in ColorQuartet – and apply them to the scans you make with Color-

Quartet.

ColorQuartet thus forms the framework for a flexible choice of color management technologies.

What you need for IT8 calibration

• To IT8-calibrate your scanner, you will need an IT8 calibration target and the corresponding

reference data file. IT8 calibration sets with both items can be purchased from the major film

suppliers (Agfa, Kodak, Fuji, etc.).

• Separate targets are used for calibrating transmission and reflection. For best results, use a

target made with the same type of film as the originals you will be scanning.

• NOTE: Calibration targets that are not properly stored may deteriorate with time, which

reduces their validity. This is particularly true of the reflection target, which should not be

exposed to light when you are not using it.

• To keep your targets in good condition, return them to their packaging after use, and store

them in a place that is cool, dry, and dark.
